Today we removed the bellows duct between PR2 and BS. The duct was detached from the PR2 chamber and sat on the floor. Then, we tried to move the duct horizontally by a chain block but the chain block and the duct were dropped. The falling length of the duct is about 20 cm.
No one was injured.
The chain block hit the duct and the duct was damaged. We will use a spare bellows duct here.
